Abstract

La présente invention concerne circuit intégré intelligent. Ce circuit intégré intelligent est caractérisé en ce qu'il possède un processeur principal (1) et un système d'exploitation exécutant un programme principal (P1) pour constituer un processus principal réalisant des tâches, au moins un processeur secondaire (2) capable d'exécuter concurremment au moins un programme secondaire (P2) pour constituer au moins un processus réalisant des tâches, des circuits d'alimentation (6) communs entre les processeurs et des moyens permettant de s'assurer que le ou les processus secondaires d'énergie similaire et de signature de fonctionnement différente, s'effectuent concurremment avec le processus principal en induisant dans les circuits d'alimentation, de façon continue ou intermittente, des perturbations énergétiques qui se superposent à celle du processus principal pour réaliser un brouillage continu ou intermittent.

The present invention relates to intelligent integrated circuit. This intelligent integrated circuit is characterized in that it has a main processor (1) and an operating system running a main program (P1) to constitute a main process performing tasks, at least one secondary processor (2) capable of concurrently executing at least one secondary program (P2) to constitute at least one process performing tasks, common power supply circuits (6) between the processors and means for ensuring that the secondary energy process or processes similar and different operating signature, are performed concurrently with the main process by inducing in the supply circuits, continuously or intermittently, energy disturbances which are superimposed on that of the main process to achieve a continuous or intermittent interference.
